Miniature Rose Plant Named &#39;KORone006&#39;

ABSTRACT

A new and distinct variety of Miniature Rose Plant, herein referred to by its cultivar name, ‘KORone006’, is provided which forms attractive, double, yellow colored blossoms. The vegetation is vigorous and the growth habit is upright. Attractive ornamental foliage is formed. The new variety is particularly well suited for providing distinctive ornamentation in the landscape.

Botanical/commercial classification: Latin name—Rosa hybrida. Common name—Miniature Rose Plant.

Varietal denomination: ‘KORone006’.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to Plant Breeders' Right Application Number 2018/1393, which was filed at Community Plant Variety Office in the European Union on May 28, 2018, the contents of which are hereby incorporated by reference for all purposes.

SUMMARY OF THE INVENTION

The new variety of Rosa hybrida Miniature Rose Plant of the present invention was created during 2013 at Offenseth-Sparrieshoop, Germany by artificial pollination wherein two parents were crossed which previously had been studied in the hope that they would contribute the desired characteristics. The female parent (i.e., seed parent) of the new variety was an unnamed seedling (non-patented in the United States). The male parent (i.e., pollen parent) of the new variety was the ‘KORpedia’ variety (U.S. Plant Pat. No. 19,638).

The parentage can be summarized as follows:

unnamed seedling x ‘KORpedia’

The seeds resulting from the above pollination were sown and small plants were obtained which were physically and biologically different from each other. Selective study resulted in the identification of a single plant of the new variety.

It was found that the new Miniature Rose Plant of the present invention possesses the following combination of characteristics:

-   -   (a) forms attractive, double, yellow colored blossoms,     -   (b) exhibits an upright growth habit,     -   (c) forms vigorous vegetation, and     -   (d) forms attractive ornamental foliage.

The new variety well meets the needs of the horticultural industry. It can be grown to advantage as ornamentation in parks, gardens, public areas, and in residential settings. Accordingly, the plant is particularly well suited for growing in the landscape.

The new variety can be readily distinguished from its ancestors. More specifically, the unnamed seedling seed parent exhibits a darker yellow colored flower and smaller flowers compared to the new variety; also the unnamed seedling seed parent exhibits a medium, bushy growth habit, while the new variety exhibits an upright growth habit. Additionally, the ‘KORpedia’ variety (i.e., pollen parent) exhibits white colored flowers, an upright to bushy growth habit and is moderately fragrant, while the new variety exhibits yellow colored flowers, an upright growth habit, and lacks a fragrance. Moreover, the new variety can be readily distinguished from non-parental related similar varieties. For example, the ‘Wekamanda’ variety (U.S. Plant Pat. No. 9,591) exhibits larger diameter flowers with higher number of petals compared to the new variety, and displays a less brilliant yellow colored petal when opening compared to the new variety.

The new variety has been found to undergo asexual propagation in Klein Offenseth-Sparrieshoop, Germany by a number of routes such as vegetative cuttings. Asexual propagation techniques in Germany, such as vegetative cuttings, have shown that the characteristics of the new variety are homogeneous, stable, and strictly transmissible by such asexual propagation from one generation to another. Accordingly, the new variety undergoes asexual propagation in a true-to-type manner.

The new variety has been named ‘KORone006’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph shows, as nearly true as it is reasonably possible to make the same in color illustrations of this character, a typical specimen of the new variety. The illustrated rose plant of the new variety was approximately twelve weeks of age and was observed at Klein Offenseth-Sparrieshoop, Germany while growing indoors on its own roots in 6.0 cm containers.

DETAILED BOTANICAL DESCRIPTION

The chart used in the identification of colors is that of The Royal Horticultural Society (R.H.S. Colour Chart, 2015 edition). The terminology which precedes reference to the chart has been added to indicate the corresponding color in more common terms. The description is based on the observation of a one-year-old specimen of the new variety, observed during February, while growing in a one-gallon container on its own roots in a greenhouse at Cochranville, Pa.

Plants of the ‘KORone006’ variety have not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotypic expression may vary somewhat with changes in light intensity and duration, cultural practices, and other environmental conditions.
